Prestressing systems have developed over the years and various companies have
patented their products. Detailed information of the systems is given in the product
catalogues and brochures published by companies. There are general guidelines of
prestressing in Section 12 of IS 1343: 1980. The information given in this section is
introductory in nature, with emphasis on the basic concepts of the systems.
The prestressing systems and devices are described for the two types of prestressing,
pre-tensioning and post-tensioning, separately. This section covers post-tensioning.
Section 1.3, “Pre-tensioning Systems and Devices”, covers pre-tensioning. In post-
tensioning, the tension is applied to the tendons after hardening of the concrete. The
stages of post-tensioning are described next.
